2001 NISSAN ALTIMA engine overheat

WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
cBe certain your vehicle maintains a level
position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle if
it has an abnormal nose-up or nose- down
condition; check for improper tongue load,
overload, worn suspension or other pos-
sible causes of either condition.
cAlways secure items in the trailer to
prevent load shift while driving.
cBe certain your rear view mirrors conform
to all federal, state or local regulations. If
not, install any mirrors required for towing
before driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering
stability and braking performance will be
somewhat different than under normal driv-
ing conditions.cAlways secure items in the trailer to
prevent load shift while driving.
cAvoid abrupt starts, acceleration or
stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.
cAlways block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if
you must do so, and if your vehicle is
equipped with an automatic transmis-
sion, first block the wheels and apply the
parking brake, and then move the shift
lever into the P position. If you move the
shift lever to the P position before block-
ing the wheels and applying the parking
brake, transmission damage could occur.
cWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, downshift
the transmission to a lower gear and
reduce speed to reduce chances of en-
gine overloading and/or overheating.
cIf the engine coolant rises to an ex-
tremely high temperature when the airconditioner system is on, turn off the air
conditioner. Coolant heat can be addi-
tionally vented by opening the windows,
switching the fan control to high and
setting the temperature control to the
HOT position.
cTrailer towing requires more fuel than
normal circumstances.
cAvoid towing a trailer for the first 500
miles (800 km).
cHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule.
cWhen making a turn, your trailer wheels
will be closer to the inside of the turn than
your vehicle wheels. To compensate for
this, make a larger than normal turning
radius during the turn.
cCrosswinds and rough roads will ad-
versely affect vehicle/trailer handling,
possibly causing vehicle sway. When
being passed by larger vehicles, be pre-
pared for possible changes in crosswinds
that could affect vehicle handling. If
swaying does occur, firmly grip the steer-
ing wheel, steer straight ahead, and im-
mediately (but gradually) reduce vehicle

speed. This combination will help stabi-
lize the vehicle. Never increase speed.
cBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
cTo maintain engine braking efficiency
and electrical charging performance, do
not use fifth gear (manual transmission)
or overdrive (automatic transmission).
cAvoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
When towing a trailer, change the trans-
mission fluid more frequently. For addi-
tional information see the ``Mainte-
nance'' section earlier in this manual.DOT (Department of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Tempera-
ture A
Treadwear
Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified govern-
ment test courses. For example, a tire
graded 150 would wear one and a half
(1-1/2) times as well on the government
course as a tire graded 100. However,
relative tire performance depends on actual
driving conditions, and may vary signifi-
cantly due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction AA, A, B and C
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades repre-sent the tire's ability to stop on wet pave-
ment as measured under controlled condi-
tions on specified government test surfaces
of asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING
The traction grade assigned to your ve-
hicle tires is based on straight-ahead
braking traction tests and does not in-
clude acceleration, cornering, hydro-
planing, or peak traction characteristics.
Temperature A, B and C
Temperature grades are A (the highest), B,
and C. They represent a tire's resistance to
heat build-up, and its ability to dissipate
heat when tested under controlled condi-
tions on a specified indoor laboratory test
wheel. Sustained high temperature can
cause tire material to degenerate, reducing
tire life. Excessive temperatures can lead to
sudden tire failure. Grade C corresponds to
a performance level which all passenger car
tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades A
and B represent higher levels of perfor-
mance on laboratory test wheels than the
minimum required by law.
